核能譜學的標準多通道分析器頻率分布圖數據交換格式This algorithm increases the speed and accuracy of the motion vector search in intra - frame / inter - frame model selection, i proposed an adaptive selection method of intra - frame / inter - frame prediction model, based on tmn recommendation. in this paper, chapter one introduces the needs for low bit - rate video compression and relevant standards. chapter two first introduces briefly some common image compression methods, then emphases on the algorithms used in h263 + encoding and decoding
本論文第一章概述了當今世界對甚低碼率視頻圖象壓縮編碼的需求以及相關的國際標準；第二章簡要介紹一些具體的圖象壓縮編碼方法，對于在h . 26x編解碼器中運用到的圖象壓縮演算法給予了重點介紹；第三章詳細探討了h . 26x系列標準，對于重點和難點部分作了詳細的闡述；第四章是具體的編解碼器設計以及核心演算法描述；第五章是h . 26x編解碼器在局域網視頻傳輸中的一個具體運用。National knowledge power bureau bureau chief king the evd standard accept when gather newsing reporter think, in the evd development process international rule of the right of knowledge of application of academic association of beginning of inside, local business enterprise is with the knowledge power strategy, become own core technique with standard, for the positive and international competition backlog of chinese business enterprise experience, grew with developped the own core competition ability to provide for chinese business enterprise good draw lessons from. according to all, the that new - released evd adoption have the right of independence knowledge compress the calculate way under the same code rate born and better than ratio ac 3 quantities s, come to a now the international and last compress the realm s advanced level
國家知識產權局局長王景川就evd標準接受記者采訪時認為，在evd的研發過程中，國內企業開始學會運用知識產權國際規則和知識產權戰略，形成自己的核心技術和標準，為中國企業積極參與國際競爭積累經驗，為中國企業培育和發展自己的核心競爭力提供了很好的借鑒。據悉，新推出的evd採用具有自主知識產權的音頻壓縮演算法eac在相同碼率下生成優于杜比ac 3質量的音頻，達到了目前國際上音頻壓縮領域的先進水平。On the base of it, a piece of data collection special chip with a core of fft is designed with vhdl ( vhsic hardware description language ) in the way of top down system design method, which can finish harmonic analysis and measure the voltage, current, frequency and power of the electric power system
在此基礎上，使用標準的硬體描述語言vhdl設計出一個fft變換內核，並以該內核為核心、採取自上而下的系統設計方法完成了一個電力系統數據採集專用晶元的設計，實現對電力系統的電壓、電流、頻率、有功和無功功率等參數的測量以及各次諧波分析。In the scheme, not only the rtlinux ' s double kernel structure and its virtual interrupt are adopted, which make the standard linux process as the lowest priority one in the real - time kernel, but also the 8254 is set to work in the one - shot model by using the kurt ' s utime package, which improves the clock frequency of the os and reduces the cpu ' s extra burden
這種新的實時化方案利用了rtlinux的雙內核體系結構和中斷虛擬機技術，將標準linux進程作為實時內核的一個優先級最低的任務進行調度；同時還利用了kurt中utime軟體包將定時/計數器8254置為one - shot工作模式，從而既提高了操作系統的時鐘頻率，又解決了cpu額外負擔過重的問題。分享友人
